According to the regional security complex theory, Afghanistan had been among the insulated countries by September 11th, but afterwards, Afghanistan couldnot have been categorized under insulated countries. It has entered South Asian Security Scenarios, and some researchers believe that it is part of this regional security complex. This research is focused on what impacts the non-security dynamics have had on Afghanistan exit from insulation status and joining the South Asian Regional Security Complex. In addition to security interdependence, existence of amity and enmity patterns, geographical proximity, presence of at least two powerful and effective actors, and the cultural and racial correlations are characteristics of every regional security complex. Some of these cases refer back to non-security dynamics, which have been discussed in this research. Issues such as cultural, ethnicity and sectarian contradictions, and a set of economic cooperations, and also Afghanistan membership in SAARC Organization can be considered as security dynamics in the region.
